If you configure it correctly you do not have to add it by hand. To test
it do ifdown eth0 ; ifup eth0 Assuming eth0 is the connection to the internet.

Since you do not show the output of ip ro, ip addr, ifconfig or route it is
kind of hard to say what is going on. Let me assure NOZEROCONF=yes does work.
You have to restart the interface that the 169.* route is on.

You spelled it wrong. it is NOZEROCONF= and if you put it in
/etc/sysconfig/network you only need it in 1 place for all of the interfaces.
IOW take it out of ifcfg-eth* and put it in network.

Not sure about this. For sure static will work.

What is this? Either put in the correct value or rm it entirely?

You set the gateway here and then... See below.

Same question as above.

It looks like you are setting your default route to ""

AFAIK these are wrong. There are supposed to be routes in there.
If you are not adding static routes (and until you get the basics working
you should not be) the file is not needed.
If you want to fix this show the output of "ip add" and ip ro. Then we can
see what is going on. Fixing this kind of stuff is simple but you have
to troubleshoot it logically or it will never work.
Also suggest you whack the GATEWAY= statments out of ifcfg-eth* and put
1 GATEWAY=ip-addr-of-your-gateway statment in /etc/sysconfig/network.
Barring that use system-config-network to set it up. It will "just work"
assuming you feed it the correct information. :-) If it for some reason still
does not work show the output of "ip ro" and "ip add" Also what show the
output of iptables -L. If there are rules in there turn off iptables until
you get basic networking working.
Make your /etc/sysconfig/network look something like this:
NETWORKING=yes
HOSTNAME=sylvester.rogueind.com
GATEWAY=192.168.0.1
NOZEROCONF=yes
The above works.

Notice, no zeroconf address? :-)
